JOHN F. TALLEY AND JOHN M. \VADLINGTON, OF UPTONVILLE, KENTUCKY.

WAGON-BRAKE.

SPECIFICATION forming part of Letters Patent No. 225,891, dated March23, 1880.

Application filed December 18, 187.).

To all whom it may concern:

Be it known that we, J. FREDERICK TAL- LEY and JOHN M. WADLINGTON, ofUptonville, in the county of Hardin and State of Kentucky, have inventeda new and useful Improvement in Self-Acting \Vagon-Brakes, of which thefollowing is a specification.

Figure 1 is a plan view of our improvement. Fig. 2 is a sectional sideelevation taken through the line as .r, Fig. 1.

The object of this invention is to furnish brakes for wagons and othervehicles so constrncted that the brakes will be applied automaticallywhenever the horses cease to draw.

A represents the rear wheels, B the forward wheels, 0 the rear axle, Dthe forward axle, E the rear bolster, F the forward bolster, .(lr therear hounds, H the forward hounds, I the reach, and J the tongue, of awagon. K is the brake-bar, which has brake-shoes L attached to its ends,and slides back and forth in long keepers M, attached to the hounds G.

The brake-bar K is pressed back against the wheels A by a curved orhalf-elliptic spring, N, secured at its middle part to a block, 0,attached to the bounds G in front of the said brake-bar K. The ends ofthe spring N rest against the forward side of the brake-bar K.

To the hounds G is firmly attached a semicircular bar, 1, to the ends ofwhich are pivoted the ends of two bent levers, (2.. The bonds of thelevers Q rest against the rear side of the brake-bar K. The inner orlong arms of the levers Q cross each other above the reach I, and theirends are bent downward, and to them are attached the rear ends of tworods, R, the forward ends of which are attached to the rearend of thelink S. The link S passes forward between the axle l) and bolster F, andis kept in place by the kingbolt T, which passes through it.

To the forward end of the link S is pivoted the rear end of the rod U,the forward end of which is pivoted to the rear end of the bar V. Thebar V rests upon the tongue J, and slides forward and back in keepers W,attached to the hounds H or to the tongue J.

To the middle part of the sliding bar V is firmly attached the center ofthe double-tree X, to the ends of which whifilctrces are attached in theusual manner.

To the end parts "of the double-tree X are attached chains or straps Y,which are also attached to or connected with the axle D, and

which are designed to prevent too much strain from coming upon thespring N.

With this construction, when the vehicle is standing still or is movingupon a downgrade the brake-shoes L will be held against the wheels A bythe action of the spring N.

hen draft is applied to the double-tree X the first eifect of the strainwill be to withdraw the brake from the wheels.

With this construction, also, the vehicle, harness, and horses will befree from any jar when starting the vehicle, and will thus be protect-edfrom injury by the shock of applying the draft to a dead resistance.

Z is a bar placed upon the rear part of the reach 1, with its forwardend in a socket or recess in the center of the brake-bar K. The rear endof the bar Z is pivoted to a lover, a, which crosses the reach l infront of the rear bolster, E, and its inner end is pivoted to a supportattached to the semicircular bar 1 or to the bolster E.

\Vith this construction, by operating the lever a the brake K will bepushed forward away from the wheels A, so that the vehicle can be hackedwithout applying the brake.

The lover a may be connected by a chain or rod with an auxiliary leverattached to the wagon-bed, so that it may be operated by the driver fromhis seat to withdraw the brake and allow the vehicle to be backed.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- 1. The bar Z, resting on the reach and pivotedat its rear to a crosslever t'nlcrumed at one end on bar I, incombination with the brakebar K, having a middle socket to receive thefree end of said bar, as shown and described.

2. In a wagon-brake, the combination, with the brake-bar K and thedouble-tree X, of the bent lovers (2, the connecting-bars It, the linkS, the rod U, and the sliding bar It, substalr tially as herein shownand described, so that the brake will be witlnlrawn from the wheels bythe application of the draft, as set forth.
